<p><P>PROBLEM TO BE SOLVED: To suppress decline in a performance coefficient of a refrigerator during cool storage operation. <P>SOLUTION: This latent heat cool storage system includes: the refrigerator 2 cooling water taken out from a water tank 1; a cool storage medium 21 in which cool storage is performed by the water cooled by the refrigerator 2; a partitioning wall 16 partitioning inside of the water tank 1 into a first section 11 where the cool storage medium 21 is arranged and a second section 12 where the cool storage medium 21 is not arranged; and a supply part (a temperature sensor 3, a valve 4 and a control part 6) supplying the water cooled by the refrigerator 2 to the first section 11 and the second section 12. An upper end of the partition wall 16 is provided in a position on the upper side from the cool storage medium 21 and the lower side from the water level. In the water tank 1, an upper inflow/outflow port 13 is provided on the upper side from the cool storage medium 21 in the first section 11 and on the lower side from the upper end of the partition wall 16. The supply part controls the amount of water supplied to the first section 11 and the amount of water supplied to the second section 12 in accordance with the temperature of the water taken out from the water tank 1. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
